your best fit is product manager. Actually the best is not to get another job if you have some savings but to start another business again. I am 35 too and just quit my job. I no longer want to participate in the rat race. I no longer want to sell my time/freedom. I want to create products that I can leverage. I want to work for my own vision and equity. I live in a country with low cost so I can probably last 3 to 5 years with my current savings.
